C)2/8:4/7=

D)2:4/5=​

Answer 1

Resposta:

A)5/6:2/8=

$\frac{5}{6} \div \frac{2}{8} \\ \\ \frac{5}{6} \times \frac{8}{2} \\ \\ \frac{40}{12} \div (4) \\ \\ = \frac{10}{3}$

B)2/9:3/6=

$\frac{2}{9} \div \frac{3}{6}\\ \\ \frac{2}{9} \div \frac{6}{3} \\ \\ \frac{12}{27} \div (3) \\ \\ = \frac{4}{9}$

C)2/8:4/7=

$\frac{2}{8} \div \frac{4}{7} \\ \\ \frac{2}{8} \times \frac{7}{4} \\ \\ \frac{14}{32} \div (2) \\ \\ = \frac{7}{16}$

D)2:4/5=

$2 \div \frac{4}{5} \\ \\ 2 \times \frac{5}{4} \\ \\ \frac{10}{4} \div (2) \\ \\ = \frac{5}{2}$
